Problem description

Automatic mirror geolocation in drakxtools-backend in Mandriva
Linux 2008.1 would fail for some locales, because it uses backward
compatibility timezone names for which there were no zone.tab entries
in timezone (bug #40184), this makes software like urpmi to not select
optimal mirrors in its automatic media/mirrors addition mode.

This update makes timezone provide backward timezone name entries in
zone.tab file to solve this issue.

Additionaly, updated timezone packages are being provided for older
Mandriva Linux systems that do not contain the new Daylight Savings
Time information for 2008 and later for certain time zones.
